- '00 5.0 in an '82 Volvo
There are a couple threads running on this conversion on this forum but am looking for some specific advice on a current problem.
The situation is that I am swapping a '00 Explorer 302 with 11k miles on it into an old Volvo. This engine has not run in 11 years. After chasing wiring problems to the point of putting it down for a few months I now have everything seemingly working. As of Saturday I finally got Henson Performance's custom tune to disable PATS to upload to the PCM.
I am now seeing electrical injector operation by seeing the PCM side of the injector drop from about 11v to 4-5v on a pattern appropriate for the starter rotation of the engine. That is for the first time. Based on that I make the assumption that the Cam Position Sensor is signaling the PCM for operation of the injectors. That does not mean that I have fuel actually spraying. There is a fuel pressure gauge permanently plumbed into the fuel supply line and it reads 65+psi.
The engine will start and run on starter fluid. That would imply that the ignition system is correctly functioning. On other cars I have been able to remove an injector and observe the spray but this one is on a rigid fuel rail inaccessible under the intake manifold and that is much more difficult.
The compression is very good as you would expect on a low mileage engine.
Compression, spark and fuel. This can't be this hard.
Any and all suggestions would be appreciated.
